IMPROVEMENT IN CARBURETER'S.

Specification forming part of Letters Patent No. 183,363, dated October 17, 1876; application led n March 4, 1876. v

To all whom it may concern Be it known that I, SAMUEL BEAN, of Cin-` cinnati, in the county of Hamilton and -State of Ohio, have invented .a new and valuable Improvement in Oarbureters; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a longitudinal vertical section of my gasreliner.

This invention has relation to apparatus for carburetin g air for illuminating purposes, as will be hereinafter more fully set forth.

In the annexed drawings, A A' designate air-engines or blowers, each one of which is composed of three cylinders, a a1 c2, and inlet and outlet pipes for air, the intermediate cylinder a1 dipping down into a Huid between the two cylinders a a2. B is a guide-rod,which passes air-tight through the head of the cylinder a?, and also through a base, B1, and to this rod B a pit-man-rod, B2, is attached, which is connected to a crank on the shaft C. The two cylinders a' a' of both engines are made to rise and fall alternately by giving rotation to the shaft O, which can be done by a weight or other convenient means.

I will here remark that the two engines A A' are constructed exactly alike, similar letters indicating like parts in both engines.

When the cylinder al of engine A is raised, air will be drawn into it through a pipe, b, which is provided with a check-valve, b', at its upper end, and when the cylinder a1 of engine A is depressed the air which was drawn into it will be forced out through a pipe, c, through a valve, c1, through a pipe, c2, and into a vertically-movable inverted cup, D, which dips into a fluid contained between two cylinders, d d'. A pipe, c, leads from a pipe which is arranged in the engine A', and communicates with the valve c1, which communicates with the inverted cup D by means of a pipe, c3.

Pipes c2 c3 are provided with valves at their upper ends, which allow air to be forced from engines A A' into the cup D, but which prevent air in cup D returning through said pipes when said cup descends, and the air which is collected in the cup D is forced out of it as it descends through a pipe, c, through a valve, f, through a pipe, g, to the carbureter. The upper end of the cup D is connected, by rods h, to the stems or lever-handles of valves cl j', so that as cup D rises and descends it will automatically regulate theentrance of air into it from the engines A A', and the escape of air from it into the carbureter.

The apparatus of which the movable cup D constitutes a part serves as a regulator or governor for the two air-engines A A', and regulates the supply of air through the pipe y to the carbureter.

E represents' a rectangular box, which is subdivided into three compartments, j j' k.

On top of this box are two chests, F G. The

chest F has a feed-tube, l, provided with a suitable cut-oft' valve, and this chest contains any suitable substance which will iilter the iiuid hydrocarbon on its way to the compartment lo, from which latter the fluid hydrocarbon passes through an opening, o, which, at times, is closed by a valve, c, and escapes into the carbureting-chambers jj', flowing in thin sheets over shelves s, arranged in a zigzag manner, as shown in Fig. 1. The two compartments j j' communicate with each other by a pipe, (not shown in the drawings,) which allows air from pipe g to circulate through both of them. The excess of fluid hydrocarbon escapes through a pipe, J, into a chamber, m, beneath a iioat, n, which is connected, by a rod, p, lever p1, and rod p2, to the valve c. When oat n rises it shuts valve o, and pre'- vents the flow of 'uid into the carburetingchambers.

From ledge to ledge of the evaporatingshelves s in the carbureting-chambers wires N are arranged, which are thickly covered with sponge or any other suitable absorbing material. This will take up the fluid from the shelves by capillary attraction, and expose a large amount of vaporizing-surface to the air which is forced through the carbureting-chambers. The carbureted air, which is now an illuminating-gas, passes through a pipe, r, into the chest G, which contains an absorbent saturated with a perfume, from which the gas escapes through a pipe, H, to be burned.

What I claim as new, and desire to secure by Letters Patent, is;-

" 1. The air-engines or blowers'A A', hevng a guide-rod, B, passing air-tight through the head of the cylinder a?, and through base B1, `in combination with pitman-rod B2 and crank-shaft C, substeintiellyiets andforthe purpose set forth.

2. The combination, substantiallyias hereinbefore described, of the airenginesorblowers A A', having inlet and outlet pipes b and of two witnesses. SAMUEL BEAN.
